Description

Driver API for PM (plib_pm.h)

Usage Example

The following example demonstrates typical usage of the PM peripheral:

 
#include "plib_pm.h"
 
int32_t configure_pm(void)
{
    /* Enter Idle sleep modes */
    PM_EnterIdle0SleepMode();
    PM_EnterIdle2SleepMode();
 
    /* Configure standby voltage regulator mode (Low Power) */
    PM_SetStandbyRegulatorMode(PM_STDBYCFG_VREGSMOD_LP);
 
    /* Enable SRAM back-biasing */
    PM_EnableStandbySRAMBackBias();
 
    /* Enter Standby sleep mode */
    PM_EnterStandbySleepMode();
 
    return 0;
}

Typedef Documentation

◆ PM_VREG_MODE

typedef uint32_t PM_VREG_MODE

Standby voltage regulator mode selection.

Function Documentation

◆ PM_DisableStandbySRAMBackBias()

void PM_DisableStandbySRAMBackBias ( void )

Disable SRAM back-biasing in Standby sleep mode.

Keeps SRAM in normal operating mode during Standby sleep, allowing DMA access.

◆ PM_EnableStandbySRAMBackBias()

void PM_EnableStandbySRAMBackBias ( void )

Enable SRAM back-biasing in Standby sleep mode.

Reduces power consumption by back-biasing SRAM during Standby mode. When enabled, DMA access to SRAM is not available in Standby mode.

◆ PM_EnterIdle0SleepMode()

void PM_EnterIdle0SleepMode ( void )

Enter Idle0 sleep mode.

Configures the Power Manager to enter Idle0 sleep mode and executes the Wait For Interrupt (WFI) instruction.

◆ PM_EnterIdle2SleepMode()

void PM_EnterIdle2SleepMode ( void )

Enter Idle2 sleep mode.

Configures the Power Manager to enter Idle2 sleep mode and executes the Wait For Interrupt (WFI) instruction.

◆ PM_EnterStandbySleepMode()

void PM_EnterStandbySleepMode ( void )

Configures the Power Manager to enter Standby sleep mode and executes the WFI instruction.

◆ PM_SetStandbyRegulatorMode()

void PM_SetStandbyRegulatorMode ( PM_VREG_MODE mode )

Configure voltage regulator mode for Standby sleep mode.

Parameters

mode	Use one of: PM_STDBYCFG_VREGSMOD_AUTO PM_STDBYCFG_VREGSMOD_PERFORMANCE PM_STDBYCFG_VREGSMOD_LP
